TEETERING DEVVICE Filed July 23,- 1945 2 Sheets-Sheet 2 f/Vl/E/VTORElmer /7- Lo/fer HTTOfF/VEY Patented May 31, 1949 UNITED OFFICELokenSioux. City, Iowa, assignor of. onehalf to. Edward B. Sta-lily,Sioux City, Iowa Application July 2a; 1945, sesame sosgcov' a claims,(01. 21 2-54) My invention relates to a teetering device;

An object of my invention isto provide ateetering arrangement whereinthe teeteringeffeet is obtained bythe manipulation-eithe hands- Withcertain membersin'. connection with. the usual manner of operation.

A further object of my invention is-to-provid'e' an arrangementwherebythe teetering effect' can be caused as desired, by oneperson-only;

A further object of my invention is to provide an arrangement whereinthe teetering effect is provided by means ofthe feet in conjunction:with the hands, etc.

A further object of my invention istoprovi'de a well balancedarrangement which is easily operable by children, is simple tomanufacture, and can be manufactured at areasonable cost.

With these and other objects in view, my invention consists intheconstruction, arrangement, and combination of the various" parts ofmy device, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and'illustrated in theaccompanying drawings, in which:

Figure 1 is a side sectional-elevation of tliedevice and takensubstantially along the lines 1-4 of Figure 2,

Figure 2 is a plan view of Figure 1,

Figure 3 is a side sectional elevation of a modifled form of thearrangement,

Figure 4 is an end detail of the base of the arrangement shown inFigures 1 to 3 inclusive,

Figure 5 is a further modification, and

Figure 6 is a plan sectional view taken along the lines 66 of Figure 5.

I have used the character It] to designate a pair of spaced base membersto which are attached the rubber bosses II for resting the arrangementupon the floor, and attached at I2 to the members 10 are the upwardlyconverging supports l3 which terminate at the apexes l4. Attached to theportions M are spacers 15. The teeter board itself is indicated by thecharacter 16 and is preferably made up of a fiat piece with its widthbeing positioned vertically as shown, the member 16 being attached at I1to the two seats 18. Attached at 19 to the member 16 and at either sidethereof, are the downwardly converging pieces 20 which are attachedtogether at 21, a further piece 22 being attached therebetween as afiller member.

Passing through the portions l4, I5, 22, and the member 16 is asubstantially strong pin 23, upon which pin the member 16 rocks.

Pivotally attached by means of suitable pins at124 are. the; lengthenedlinks 25-whi'ch are pivote ally attached. at. 26' between the pairs of ivertical arms; 21, which arms 21 straddle the member 16, Theaarms; 21.are pivotedon the lower shafts 28 which pass through the base members 10and include suitable spacers 29 attached thereto (see The members 21 arefurther braced Figure 4). at 3llsand are; attached at 31 to the handles32,

and attached at 33 across the members 2 1- are:

thefoot receiving. bars 34.

It will now be seen that children seatedupontheseatsz. Hi, When graspingthe handl es 32 and forcing them. baekwardly and forwardly in: the:

direction. of the arrows 35 will cause the arms 2 1 pivot at 2'8, atthesametime causing the links. 25 to rock the members ill 'through'thepivot. connections. at 24. Since the members arrangement, since the useof the hands: on:

thehandl'es; 32' will maintain. the rockabl'e por tionsofthedevice atany inclined: position. This manual operation also is amusing, balancesthe working parts, and makes the teetering action much easier. Thechildren can rest their feet on the cross-bar 34, and by pushing on thesame inwardly will assist in the above described action.

Figure 3 illustrates a modified form of the arrangement wherein most ofthe above described parts are used, these parts being designated by thesame characters. This arrangement, however includes a few slightchanges, and includes two pairs of vertical links 31 which straddle themember l6, and which are pivoted at 38 thereto. Pivoted at 39 betweenthe members 31 are the lever members 40 which are pivoted at 4| betweenthe members 21, the levers 40 ext-ending outwardly and being attached at42 to the foot bearing transverse bars 43. In this structure, the abovedescribed links 25 will be received between the members 31.

By manipulating the handles 32, the member IE will rock in accordancewith the action as described hereinabove, and by pressing downwardly onthe foot bars 43 the leverages exerted through the members 40 will causeth links 31 to assist in the rocking action through the pivotalengagement at 38.

Figures 5 and 6 illustrate a further modified form of the arrangement inwhich the member 16 and the seats I8 are the same, and wherein a pair ofupwardly converging braces 44 are ber l6, which arms 53 straddle themember [6.

Also pivotally attached at 55 to the upper extremities of the arms 53 isthe horizontal member 56 which terminates in the handles 51 atr tachedthereto.

It will now be seen in this latter structure, that children seated uponthe seats l8 can push forwardly and pull rearwardly on the handles 51,whereby the linkages above described will correspondingly through thepivotal engagement at 54, etc., cause the beam it to rock upon the pivot48.- It will be noted that the members 5| and 53 are at an angle to eachother substantially less than a right angle in order to provide thenecessary folding action to cause the member IE to rock.

It will not be seen that I have provided all of the advantages mentionedin the objects of my invention with further advantages being readilyapparent.

Some changes may be made in the construction and arrangement of theparts of my invention without departing from the real spirit and purposeof my invention, and it is my intention to cover by my claims anymodified forms of structure or use of mechanical equivalents which maybe reasonably included within their scope.

I claim as my invention:

1. A teetering device comprising a support, a teetering member pivotedcentrally on said support, vertical arms pivoted to the support, handlesattached to said arms for graspment by person seated at the ends of saidteetering member, said arms being attached to said teetering member 4 sothat movement of said handles will rock the same, including linkspivotally attached to the arms, brackets attached to said teeteringmember, said links being pivotally attached to said brackets.

2. A teetering device comprising a support, a teetering member pivotedcentrally on said support, vertical arms pivoted to the support, handlesattached to said arms for graspment by person seated at the ends of saidteetering member, said arms being attached to said teetering member sothat movement of said handles will rock the same, including linkspivotally attached to the arms, brackets attached to said teeteringmember, said links being pivotally attached to said brackets, footreceiving members attached to said arms.

3. A teetering device comprising a support, a teetering member pivotedcentrally on said support, vertical arms pivoted to the support, handlesattached to said arms for graspment by person seated, at the ends ofsaid teetering member, said arms being attached to said teetering memberso that movement of said handles will rock the same, including linkspivotally attached to the arms, brackets attached to said teeteringmember, said links beng pivotally attached to said brackets, furtherlinks pivotally attached to said teetering member, levers pivotallyattached to I said further links and to said arms, foot receiving barsattached at the outer extremities of said levers, whereby foot actionagainst said foot receiving members will cause further rocking action ofsaid teetering member.
